Processing of long-term Earth's electromagnetic field observations was performed using two software systems (PRC_MTMV and PTS), frequency distribution of the amplitude and phase of impedance, apparent resistivity, horizontal components of the magnetic tensor and tipper were obtained. Minimum on the descending part of K curves according to the results of a qualitative assessment corresponds to the conductor at a depth of 50-150 km.

Key words: magnetotelluric sounding, magnetovariational profiling, the Dnieper-Donets Trough.
